Volunteers’ data should be included in official monitoring reports to tackle pollution crisis, says Earthwatch

Citizen science testing of river water quality will expand this year in an attempt to make the data part of official monitoring of waterways, the head of an independent environmental research group has said.

The use of ordinary people across the country to test river water quality for pollutants including phosphates, nitrates and other chemicals has captured the imagination of thousands of volunteers. In 2024 more than 7,000 people took part in river testing “blitzes” run over two weekends by the NGO Earthwatch Europe. The research, using standardised testing equipment provided by the NGO and Imperial College London, gathered data from almost 4,000 freshwater sites across the UK.

Pragmatism will win over purism, unless the government favours early closure for car manufacturers

The main timetable is set: no new petrol and diesel cars will be allowed to be sold in the UK after 2030, and sales of all new hybrids will be forbidden from 2035. But that phasing still leaves open the critical matter – for the automotive industry, and for a couple of manufacturers in particular – of which new hybrids will be allowed to be sold until the last day of 2034.

Just the variety that comes with a socket – plug-in hybrid electric vehicles (PHEVs)? Or should old-style hybrids, such as the Toyota Prius, which have smaller batteries charged by a main internal combustion engine, also be permitted?
